We are given our time here to make a mark. A mark not for the betterment of ourselves but for our kind. A shallow man wants to be remembered for his own accomplishments, his riches, and his possessions.
Then there are men and women that want to be remembered for their talents, the love they shared, the meaning they left behind, and the light that they shown for others. Those people are the ones that inspire the rest of us to desire something more than the temporary entrapments offered by the others. Both these men leave their marks. One fades away extremely quickly while the other turns into an inspiring story that is passed on.
Then there is the person who lives a life and doesn't realize that they have not left any mark until it is too late and are depressed by the knowledge that they have lived among many and left nothing of meaning to be remembered by. They feel like it was a waste.
